What is species diversity?

Answer»

Species diversity refers to the variety in number and richness of the species in any habitat. The number of species per unit area at a specific time is called species richness, which denotes the measure of species diversity. The Western Ghats have greater amphibian species diversity than the Eastern Ghats. The more the number of species in an area the more is the species richness. The three indices of diversity are – Alpha, Beta and Gamma diversity.

Explain in short about the Westergren method of ESR.

Answer»

Erythrocyte Sedimentation Rate (ESR):

  • If a blood sample mixed with an anticoagulant like Trisodium citrate and kept undisturbed for some time in an ESR measuring tube, blood cells being denser than plasma, moves towards the bottom of tubes and settler down. The rate of setting down of the blood cells is called Erythrocyte Sedimentation Rate. The ESR measurement can be done by two methods.
  1. Westergren method
  2. Wintrobe method
  3. In most of the pathological laboratories, only the Westergren method is used for ESR testing. Hence, here this method is described.
  4. Westergreen tube is filled up to zero points with the blood containing anticoagulants. This tube is kept legitimately in a verticle position in ESR stand.
  5. After an hour the upper level of erythrocytes is read in the ESR tube. This is the value of Erythrocyte sedimentation rate.
  6. The ESR value of a healthy person is as follows:
  • Male = 0 – 16 mm per hour.
  • Female = 0 – 20 mm per hour.
  1. If the rate of ESR is more than the normal value, it indicates towards irregularities in the body. Value of ESR increases in many chronic diseases like tuberculosis and inflammatory diseases like Rheumatoid arthritis, multiple myeloma or allergy, lymphatic inflammation etc.
  2. Moreover, the value of ESR increases during pregnancy, Anaemia and with an increase in Age. These days Automated mini ESR machine is used to enhance the accuracy in the value of ESR. The machine works at a controlled temperature of 18°C. In the traditional methods, temperature regulation is not possible and a chance of 25 – 30% error exists.

Write the medical significance of Differential Leucocyte Counts.

Answer»

Write the use of ECG.

Answer»

  • It is used to detect cardiac disorders like arrhythmias, conduction disturbances; myocardial ischemia etc.
  • It reveals other findings related to life-threatening metabolic disturbances like hyperkalemia or increased, susceptibility to sudden cardiac death (Example: QT prolongation syndrome).
  • It is used to study the rate of heartbeat, and cardiac disorders such as myocardial infarction (MI), coronary artery diseases etc.

Explain in detail about the process of haemoglobin measurement in blood.

Answer»

Estimation of Haemoglobin in blood:

  • Estimation of haemoglobin in the blood is called Haemoglobinometry. Haemoglobin is a respiratory pigment found in red blood corpuscles. Chemically, it is a chemoprotection which is used for the transport of O2 and CO2.
  • Working efficiency of a person has affected adversely if due to some reason his/her haemoglobin content drops below the normal value. A value of haemoglobin less than the normal value is an indicator of Anaemia.
  • Haemoglobin content is measured with Haemoglobinometer. Traditionally Sahli’s Haemoglobinometer is used for this purpose.
  • Photohaemoglobinometer and Autoanalyzer are also used.
  • Sahli’s Haemoglobinometer:
  • This device contains a graduated tube and two standard matching tubes placed in a stand. Between the two standard tubes is placed a measuring graduated tube. In the measuring tube, N/10 HCl is filled up to zero (2 g%) point.
  • Now using the haemoglobin pipette 20 Jul (0.02 ml) blood is transferred to the measuring tube. Blood is thoroughly mixed with N/10 HCl already present in the tube.
  • The N/10 HCl converts haemoglobin into a brown coloured substance called haematin. The measuring tube is now kept in between in the two standard tubes.
  • Distilled water is added drop by drop mixing with continuous mixing to the measuring tube until the colour of the haematin solution matches with the colour of the standard tubes/comparison tubes.
  • When the colour matching between the tube is ensured, haemoglobin content is measured by observing the reading on measuring graduated tube.

3. Perineural sinus: It is ventral, small and contains ventral nerve cord. It is continuous into legs. All the three sinuses communicate with each other through the pores present between two successive points of attachments of diaphragms.

21117.

 Can simple harmonic motion take place in a noninertial frame? If yes should the ratio of the force applied with the displacement be constant?

Answer»

Yes. Consider an accelerating vehicle in which a block is attached to a spring on a smooth horizontal surface and the other end is fixed. The rest position of the block will change compared to the nonaccelerating vehicle. If the block is stretched and released it will be in a simple harmonic motion having the mean position changed to a new one. 

But the ratio of the applied force with the displacement will not be constant until we take a pseudo force into account that is mass times the acceleration of the vehicle and opposite to the direction of the accelerating frame.
